The senator made the declaration Friday during an Indian Affairs Committee field hearing in Phoenix, Ariz. The hearing was titled: "Examining the Environmental Protection Agency's (EPA) Unacceptable Response to Indian Tribes."

"I've come to the conclusion that a Department of Justice criminal investigation is merited and must now occur," McCain said.

He cited EPA employees' failure to conduct appropriate water pressure tests at the mine and adequately consult partnering federal agencies before excavating around the mine's containment plug, though they knew about the potential for a "catastrophic blowout.”

The spill "has devastated lands and livelihoods across Navajo Nation" McCain said in a statement. He said he is concerned about the EPA's "disregard for environmental issues in Indian Country."

The waste water spill at the abandoned Gold King Mine in August of 2015 dumped 3 million gallons of toxic sludge into the Animas River in Colorado, tainting waterways of three states. A report by the Interior Department in October of 2015 concluded that had the EPA properly conducted water pressure tests at the mine, the crisis could have been averted.

McCain and Indian Affairs Chairman John Barrasso subpoenaed EPA officials to testify at the hearing. Mathy Stanislaus, EPA assistant administrator for the Office of Land and Emergency Management, appeared along with Arizona Rep. Ann Kirkpatrick and Navajo and Hopi tribal leaders.

This is an "anti-accountability" administration so don't expect any action. But imagine if you will a corporation being responsible for such a disaster. The EPA would jump down their throat, throw executives in jail, force them to clean up the mess, and fine them severely.

By contrast, no one at the EPA has been fired or even demoted for this preventable tragedy.

Until we hold government to the same standard to which we hold the private sector, there can be no justice.

Senator John McCain wants to charge EPA officials with a crime for their actions that led to the disastrous release of toxic wastewater from the Gold King Mine last year.

The spill polluted 3 rivers and severely effected the lives and livelihood of several indian tribes.
